Robotic Data Help Explain Mysterious Holes

the first time oceanographers had a chance to truly monitor the unexpected gap in Antarctic winter sea ice. It was an opportunity that came about as a result of uncanny timing and a seasoned oceanographer’s knowledge of the sea.A new study co-authored by researchers from Scripps Institution of Oceanography at the University of California San Diego combines satellite images of the sea ice cover and data collected by robotic drifters and even seals outfitted with sensors to better understand the phenomenon. The research led by the University of Washington (UW) explores why this hole appears only some

Researchers to Monitor Disruptive US Gulf Current

A major $2 million scientific study led by the University of Rhode Island (URI)’s Graduate School of Oceanography will monitor disruptive ocean currents in the US Gulf of Mexico, with a long term goal to improve forecasts for safer offshore operations in the region.The Loop Current System (LCS) is the dominant ocean circulation feature in the Gulf of Mexico, influencing all ocean processes in the Gulf with implications for a wide range of human and natural activities, from oil exploration to coastal eco-systems. To date, knowledge of its underlying dynamics is limited.URI’s initial study

submarine relief of this channel has been shaped by the action of several geological processes in polar margins. The gullies are the main topographic structures “that enabled the geological reconstruction of INBIS channel,” noted Leonardo Rui, member of the Trieste National Institute of Oceanography and Experimental Geophysics (OGS) and first author of the study.“In particular,” Rui continued, “the structure and some traits of these formations –for instance, ratio between dimensions and incision depth- help understanding the possible formation mechanisms and the differentia
